为寻找哈图齐Ⅱ金矿深部隐伏矿体,研究了该矿成矿特征和主要控矿构造的空间展布规律,发现矿区内多数矿脉集中分布于不完整褶皱的核部及包古图组C1b1层中;断裂构造控矿作用明显,矿脉多发育在各级断裂的下盘或较大型断裂带内,控矿断裂有向下断续延伸的趋势,且规模未显著缩小。分析矿区内雁列式或串珠状盲矿体原生晕的分带性,发现该矿深部矿脉群的原生晕具前缘晕和尾晕共存的叠加结构。该特征是哈图齐Ⅱ金矿进行深部隐伏矿体找矿预测和评价的重要依据。
In order to search for the deep concealed orebody in the Hautaiqi Ⅱ gold deposit, the mineralization characteristics and the spatial distribution of the main ore-controlling structures in this deposit were studied. It was found that most of the veins in the mining area were concentrated in the nuclei of the incomplete fold and the paleo-packs In the layer C1b1, the ore-controlling effect of the fault structure is obvious. The veins develop more frequently in the lower plate or larger fault zone of all faults, and the ore-controlling fractures tend to extend intermittently downward without any significant decrease in scale. The zonation of the primary halo of the emeralds or beaded blind orebodies in the mining area is analyzed. It is found that the primary halo of the deep veins in the mine coexist with the superposition structure of the front halo and the tail halo. This feature is an important basis for the prediction and evaluation of the prospecting of the deep concealed orebodies in the Hetuqi II gold deposit.
